Total postemergence weed management programs are not new, but the introduction of herbicide- resistant crops has increased the interest in this strategy. The broad-spectrum activity and ability to kill large weeds with products such as Liberty, Lightning, Roundup, and others provide growers with greater flexibility in application timing than was previously available. This flexibility has raised questions whether one-pass, total postemergence programs are a reasonable weed management goal for corn and soybean production.
